摘要
本文以位于秦岭褶皱系南秦岭印支褶皱带凤县-镇安褶皱束中段的东阳石英脉型钨矿为研究对象,区内岩浆岩发育,以江口岩体及懒板凳岩体具多期次复式岩体的特征,其中懒板凳岩体为区内成矿岩体,为准铝-弱过铝质壳源S型花岗岩,矿石矿物为白钨矿、黄铁矿、黄铜矿、辉钼矿,脉石矿物为石英、方解石、绢云母等。通过对区内构造特征、岩体性质及矿体特征的分析与研究,认为该矿床成矿地质条件较好,矿床深部及外围找矿潜力较大。
This paper focuses on the Dongyang quartz vein type tungsten deposit located in the middle section of the Fengxian Zhen'an fold belt in the southern Qinling Indosinian fold belt of the Qinling fold system.The magmatic rocks in the area are developed,and the Jiangkou rock mass and the Laziandeng rock mass are characterized by multiple stage complex rock masses.The Laziandeng rock mass is the metallogenic rock mass in the area,which is a quasi aluminum weak peraluminous crust source S-type granite,and the ore minerals are scheelite,pyrite,chalcopyrite,and molybdenite,Gangue minerals include quartz,calcite,sericite,etc.Based on the analysis and study of the structural characteristics,rock mass properties,and ore body characteristics in the area,it is believed that the ore-forming geological conditions of the deposit are good,and the prospecting potential in the deep and peripheral areas of the deposit is large.
